Offering many of city’s best restaurants and shops set amid classic New York architecture, the Flatiron District is no longer under the tourist radar. At 23rd Street is the famous triangular Flatiron Building, which makes a good picture no matter what angle you photograph it from. Be sure to look up at the elegant architecture as you stroll the streets- much of this neighborhood is part of a historic district that was home to many of the city’s most famous department stores at the turn of the century. At the northern end of the neighbourhood, Madison Square Park is best known for being the home of a famous burger shack, but it can also be a quiet refuge to spend an afternoon, and it frequently hosts interesting public art exhibits. In the lower part of the Flatiron District you'll find Union Square, a bustling crossroads at all times of day and night.
